NUT-LOCK- Specification of Letters Patent.

Patented April 23, 1907.

Application filed July '7, 1906. Serial No. 825,164..

To aZZ whom it may concern:

Be it known that I, THOMAS R. I'IORN, a citizen of the United States,residing at Marquette, in the county of Marquette, State of Michigan,have invented certain new and useful Improvements in Nut-Locks; and I dohereby declare the following to be a full, clear,-and eXact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention has relation to nut-locks for holding a series of nuts onthe bolts extending through the fish-plates of a railway-rail againstturning back or becoming loose.

It is the object of my invention to provide a nut-lock of the classmentioned that operates alone to keep the nuts from turning and will notinterfere with ormodify the spiking of the rails and fish-plates to theties.

It is a further object of the invention to provide means for keeping thenut-lock plate from tipping either up or down from its correct position.

The nature of the invention is to be ascertained from the foregoingstatements in view of the annexed drawings, forming a part of thisspecification, of which drawings Figure 1 is a side elevation. Fig. 2 isa section on line 2 2 of Fig. 1.

The same figures of reference designate the same parts or features, asthe case may be, wherever they occur.

- In the drawings, 5 5 designate the ends of the'two rails joined by themeans represented in connection therewith. 6 6 are the fishplates. 7 and8 are respectively the bolts and nuts securing the fish-plates to theweb of the rails. Spikes 9 are employed for securing the inclinedflanges of the base of the rails and fish-plates to the railway-ties 10.All of the said parts are of usual construction and arrangement.

11 is the nutlocking plate constituting a part of my improvements. Thisplate is made as light as is consistent with the strength required of itto perform its necessary functions. The said plate 11 is provided on itsupper edge with a straight vertical 12, which fits against one of theflat sides of each of the nuts 8 underneath the same. From the vertical12, the plate 11 is inclined downward and outwardly, covering theinclined flanges of the fish-plate and rails as well as the usualspikesthat secure the rails and fish-plate to the ties. line where theheads of the aforesaid spikes are located the nut-locking plate 11 ispro and forming the lower outer edge of the nut' locking plate 11 thelatter is provided with a ledge 16, by which the last-mentioned plate isspiked to the ties 10 through the medium of additional spikes 20, all asis clearly represented in Fig. 1 of the drawings. By the means stated itwill be seen that the means for securing the nut-locking plate inposition are entirely independent of the spikes which fasten the railsand fish-plate to the ties, so that the latter can be constructed andused entirely with respect to fastening down the rails and fish-platesand need not be in any way modified because of the presence of thelocking-plate.

18 designates a small plate, secured by screws or threaded bolts tappedthrough its edge and surrounding parts to the under side of the saidelements to hold the nut-locking plate from tipping either up or down,which its outer edge is inclined to do under some circumstances. Saidplate is arranged at a point between'two ties, so that it does notinterfere with the construction or arrangement of other parts.

What is claimed as the invention is A nut-lock for the series of nuts ata railway-rail joint consisting of the combination with the said nuts,the rails, ties, and fishplate, of the nut-locking plate having a flangeon its upper side fitted againsta flat side of the nuts underneath thesame, and extending over the base-flanges of the rails, fish-plate, andheads of the rail-securing spikes, the nutlocking plate being providedwith a right an gular rib along the line of the spike-heads, said ribbeing undergrooved for the reception of the spike-heads and having ahorizontal ledge on its outer edge whereby it is independently spiked tothe ties.

In testimonyv whereof I a'l'liX my signature in presence of twowitnesses.

THOMAS R. HORN.
